Abstract: A data processing system is disclosed which comprises a data processor and memory control device for controlling the access of information from the memory. The memory control device includes temporary storage and decision ability for determining what order to execute the memory accesses. The compiler detects the requirements of the data processor and selects the data to stream to the memory control device which determines a memory access order. The order in which to access said information is selected based on the location of information stored in the memory. The information is repeatedly accessed from memory and stored in the temporary storage until all streamed information is accessed. The information is stored until required by the data processor. The selection of the order in which to access information maximizes bandwidth and decreases the retrieval time.

Abstract: The pulse impact mechanism (12) has a rotation element (13), joined to a driving shaft (14), in which a receiving opening (16) for a core (17) is configured concentrically with the rotation axis (15). The core part (17) is joined in rotational engagement with a driven shaft (25). In addition, rotation element (13) has a radial bore (18), extending perpendicular to the rotation axis (15), in which a reciprocating piston (19) is received in radially displaceable fashion. The reciprocating piston (19) has a through opening (20) through which core part (17) passes. The reciprocating piston constitutes, with its inner surface facing toward the core part (17), a control surface (36) that cooperates with a control track (37), with control cam (38), configured on the core part (17). When a relative rotation of rotation element (13) and core part (17) occurs, the reciprocating piston (19) executes a stroke in the radial direction.

Abstract: In a power-driven, hand-held tool provided with a pneumatic motor, the stator of the motor is comprised of a central tube of steel and two end flanges of plastics applied onto the central tube by injection molding. The impeller rotor of the motor is supported within the stator and assembled with the stator to form a complete motor assembly which is supported within the cylindrical housing of the tool by means of elastic rings which protect the tool against oscillations. The motor assembly can be assembled and tested outside the tool housing.

Abstract: To remove, by suction, chips and debris arising in operation of a hand-cutting tool, for example a sheet-metal nibbling tool, a saber saw, or the like, an ejection nozzle is surrounded by a preferably plastic body defining, internally a Venturi, and externally of the ejection nozzle a vacuum, underpressure or suction chamber which is connected through a preferably flexible hose to a suction pick-up nozzle, removably attached adjacent a reciprocating tool at the working or cutting head of the tool. The suction pick-up nozzle preferably includes a chamber in direct air communication with the tool so that chips which arise in tool operation are directly drawn into the pick-up nozzle for removal, by air flow suction, through the suction duct and to a collecting and disposal hose.
